- 摘要:
- 为探讨草莓果实中吡虫啉残留的品种间差异，研究了8个品种草莓果实中吡虫啉的残留动态。结果表明：吡虫啉在不同品种草莓上的降解半衰期在2.1～4.4 d之间；随着时间的延长，吡虫啉在草莓果实中的残留量逐渐降低；其中“槐花蜜”、“卡姆罗莎”、“幸香”和“明宝”4个品种的半衰期均在2 d左右，“弗吉尼亚”的半衰期最长，为4.41 d；该试验中有6个草莓品种的吡虫啉半衰期均在4 d以内，属于低农药残留的基因型，值得在生产上推广应用，有利于提高草莓的食用安全水平。
- Abstract:
- Imidacloprid degradation dynamic of eight varieties of strawberry were studied to explore the difference of different varieties strawberry.The results showed that the half-life period of imidacloprid on different varieties of strawberry was between 2.1~4.4 days.With the extension of time,imidacloprid residues in strawberry fruit decreased.The half-life period of imidacloprid of ‘Huaihuami’,‘Kamm Rosa’,‘Xingxiang’ and ‘Mingbao’ was about 2 days.The half-life period of ‘Virginia’ was 4.41 days,which was the longest.There were 6 strawberry varieties in this experiment which half-life period of imidacloprid was within 4 days,belongs to the genotype of low pesticide residues,worthy of popularization and application in the production,to improve the edible safety of strawberry.
